To all inkom t may concern.' Y. y p

Be it .known that I, CHAnLns F. Henn,

vJr., a citizen ofv the vUnited States of America, and resident of Cincinnati, in the county of Hamilton and State of @3h107 have invented a new and useful Machine for Soldering the Joints of Sheet-Metal Gansj` of which the following is a specification.

This invention-relates to amachine for soldering the joints or seams of the bodies 4of sheet metal Lcans and particularlygthe l a machine adapted tosolder the joints of the bodies of sheet metal cans in such a manner that the solder Will-permeate the joints and become sweated therein'. v

.A further object is'to produce aniacliine adapted to solder the joints of can bodies more rapidly and more thoroughly than has been done'heretofore'. Y v

A further object is to vproduce machine for soldering the joints'of `the bodies of sheet metall cans with a minimum amount 'of solder, whereby the cost of production fof can'bodies having ksoldered joints, is inaterially reduced. f

These and other obj specificationy and illustrated in the accompanying dravvings,-in which: f

The niacliine upon which the several devices above ynamed are mounted, consists of a frame vforlr l0 carrying, a forni ll. over Which the' bodies-of the cans are passed in vtheir passage through the machine. Located on each side of ythe form are theconveyers 12 and 13,L these convey/ers being adapted to engage. they canbodies in order toicarry them along the form. is the can body passes from the can-shaping forni not shown, the first rmechanism ivith-ivhich it `Fach of the devices above men-f comes into engagement is the yacid spreading 4 mecliaiiisinlll adapted to spread acid upon the joiiitlocated uppermost when the can body fis `placedupon theform il. As the body continuesfin itsfinoveinont over the form the next mechanism' Witirwhich it engages is'the solder feedingjmechanism'15, this mechanism being adapted to feed ordinary Wire solder in suflicient amount to solder the `can joints as the bodies are passed beneath it. lThe amount of solder fed to the can bodies is rendered adjustable by the lsoldering `mechanism and solder is fed to the can bodiesonly when the can contacts the lize the solder fed by the nieohanisin i5 andvvliicli fuses the solder into the joints `of the can'bodiesv as they passbeneath it.'y

Afterhaving passed device 19the solder` wing `operations .of the can body are ,come y pleted and it is passed from the form 11 y yto'this Cain is a clutch member 45 carrying linker connecting rod 38 Which extends from karm 33 to a block 39 reciprocally y mounted inthe slot d() formed in a rotating disk. 41, has been provided. Block 39 is adrsprockets 4G vand'li'f" through either one ot ivhich driving'poiver is disseminated. Cooperatingwith clutch member ll5 is its complemental member 48.1; this member being secured toshaft 4:2 and normally spring pressed linto engagement with member i5 by means of a spring i9 bearing against it at one end and at yits opposite end against the collar 50 secured to the shaft 42. Cam Mis provided'ivith an elevated portion 51 to be brought into engagement with a roller 52 mounted on a swinging arm 53 carried bythe frame. This arm 53 is a bell crank iny shape, the lower arm 54 of which, is se- 'cur dirto a link 55 controlling the moveents of a solder shearing knife 56 reciprocallyfmounted in a slide 57 located adjacentfto the strip of vWire solder. Coper-4 ating with this knife is another lni'fe53, between which and knife 56 thesolder is ted. Clutohmember 4:3 `is provided With al tooth 59 which is engaged by a paivl 60 tending from a lever, 61 pivotally mountedy on a shaft'62 extending from side to side of the traine carrying the soldereeding f mechanisma vThe loiver end of this lever 61 is connected with a link 2oEL which is in turn connected iviththe upper end of a tiifffer bei. Sqtho lower end of which is located in the path of the can bodies passing through the machine. The trigger 63 is connected with a spring 64 adapted normally 'to retain the pavvl 60 in vengagenient ivithclutch Vmember tooth 5D, so that operation of the solder V:')Fceding mechanism 1s prevented except when trigger@ is engaged byu can body p ssingthroughV the' machine, immediately upon engagement oi: the trigger by a can body, the solder feeding mechanism released by disengagement ot pawl 60 from 'tooth 59 anda strip off solder is iedbetivcen 'feed rollersv 26 and 2? and between vknife bladesf56 and 58, knife blade 56 shearing oit a strip of the desired lengtlnas soon as hump 51 engages'roller 52 of arm 53.A

yThe next device eneounteredby the can body'inV vits passage through the machine is the soldering device. This device consists of g soldering irons 65fand 66 located in alinek9() which during` vrotation of the cam is adapted ment with one another and in positionto engage the uppermost joint of the can,l body vas. it passes over form 11. Mounted inthe front soldering iron 65 is a tube 67 through cwhich thejstrip of solder-which has been Vsheared off after operation of the solder A-fecding mechanism, falls. .These irons 6,5 v` and 66 are maintained ata high temperature by gasflames issuing from gas supply nozzles located rin a y'gas supplyv pipe 68 locatedy above the irons, the irons being formed hollow soA as to retain the heat transmitted to them by the gas llames. T he temperature of these irons ismaintained suciently high to meltfthe solder dropped into thetubej- 67 from the solderL feeding mechanism. After yhaving passed the soldering irons the uppermost joint of the canbody is nished.

At this time the canbody is brought finto engagement with the second acidj spreading device 17. This deviceis especially designed to operate upon the` lowermost joint of the body and consists of a roller 69 haying a felt surface, this roller being adaptedl to engage the surface of an acid feeding roller 70 located in anacid'pan 71 mounted on the frame ofthe machine. During its passage through this device, the canbody engages roller 691and lifts it away'from roller (0 so 3.0 thatthe oint passes between rollers 69'and 70. l Roller v69 is mounted on a swinging arm -72 provided for Vthis purpose. Continued vmotion of the ,can body brings its front edge into engagement with a trigger 78v adapted tol operate the solder feeding' device 18.

This device is in all respects like the construction of device 15 and for this reason ,the

above description'of device 15 also appliesy to Vdevice 18. Having caused operation of V:40 Vdevice` 18, the vsolder fedV thereby, drops through atubeV 74 and Zinto a tube 7 5 extendmg from soldering iron 76 forming a portion of soldering'device 19 which Athe can v.body next engages iin its passage through the machine'. The construction of` device 19 is identical'with that offdevi'ce 16 and for kthis `reason* theabove. description of device 16 applies equally tordeviceVv 19. 'Howeven the soldering irons Z6 and?? as wellas tube 'Z5' and burners 78 and 79 of soldering device 19,'are located upon the interior or the formv 11- and consequently upon the interior of the `can during itsV passagethrough the machine. ln addition to this, because of its A interior location, .soldering device 19 op- -165 Spider S4 SMPIQVidGd--Witha hollDWiSr-edle erates upon the interior of the `lower Ijoin-t of the can bodiesinstead of upon the exte-` rior ofthe 4joint'as does solderingY device 16 lin` its operation upon ytherupper j ointof the can body. f

, 97', 98 and 99 mounted in brackets 100, such Y as i disclosed in Fig. 4, located at opposite ends andi on oppositervsidesfof the Vframe-10.

The chains 12 andl 13are provided with lugs 101iand 102 whicha're spaced at intervals on with each of the acid spreading,gso`lder feeding and soldering mechanisms; In order 4to support the,J chains v between the sprockets, Y 'angle'irons'laand 12?? arelprovided for ch'ain 12 ilandangle `irons 13a and-lbare vprovided'for chain 13.- V

The, driving mechanism `for operating; the

f various elements consistsof a driving shaft 108V located at the'receiving end ofthe masa Locatedon eachside of thefform'; are the Y conveyer mechanismsgconslstlng,, of y the Y chine.;,and lexteildingtransversely of lthe A frame 10. This shaft is provided with bev- 'eled gears104 and 105 which mesh with beveled gearsv 106 and107 secured to shafts V108 and 109 extending longitudinally of the ,fmachine .I and adjacent toA the,v bed thereof.

Shaft :108 is journaled in bearings 110, 111

kThus krwhen shaftv103 uponl which driving pulley 118- isj mounted, 'is rotated, the conveyer `chains will be operated bythe above described mechanism. 'the .side oppo x siteto that to which the driving'pulley 118 is `cfonneeted,-a lpulleyY 119 -is -mounted on shaft y103; 'this pulley .having ar-,belt 120 passing over-fa rsmall pulley 121-"wfhich rotatespacid spreading roller 70.

of Vsoldering iron 65, just as the front edge ofy the -top joint of the can body reaches this joint.` Continued passage ofthe can causes the solder which has been melted rby -iron toQbe spread over ythe joint and to be sweated into `it in the presence of the 15. As soon'as thefront edge of the can leaves the last of the top joint soldering 'ironsf the forward edge of the lower joint is brought between rollers 69 and 70, roller 69 spreading acid over the bottom joint in Vthesame manner that rollerk 14 previously spready acid over the top joint. Substantially ysimultaneous with the engagement ofl thelower joint with -roller 69, theforyward edge at the top of the can body is brought into engagement'with trigger 7 3.

Thiscauses'operation of the second solderv feeding vdevice 18 in the samemanner as the first solder feeding devicewas operated. However, the solder delivered by this device passes `through tube 74, into tube 75 and into the front portion of soldering iron 76, where the solder is melted. By this time acid distributed to the joint by vacid rollerkk n,

the forward-edge of thebottom jointof f the can body engages soldering, iron 76 and thepmeltedsolder in the presenceof the acid distributed by'roller 69, is spread overfthe lowen joint land is swe'ated into it in the same manner that the solder was spread and ysweated into the upper jointv of the can body. After leaving soldering irons 76 and 77 thecan body is engaged by rollers 89 and 90 and is removed from the machine. After the can bodiespassthe triggers 63 rv'and y73,' the springs 64 act to return their connected movable parts to normalpositions and thereby stop the operation of the solder feeding` mechanisms. At this Y point 'the can'fis taken up by the usual Hanging, curlingY and bottom attaching mechanisms andis completed.4 e
